SPEGlIFICATION forming part of Letters Patent No. 748,835, dated January 5, 1904.

To all whom it may concern.-

Be it known that I, CAESAR R. BAN'NIHR, a

citizen of the United States of America, and a resident of the city of New York, borough of Manhattan, county and State of New York,

have invented certain new and useful Improvements in Heaters, of which the following is a specification.

. The object of this invention is to produce a heat-radiating device for a heater of economical construction which receives its heat from the gaseous products of combustion arising from the flame of a gas or other burner which the device is made and the construc tion should be such that it will suitably'conform to the flame and will withstand the heat from the flame without injury or change of form.

Other objects of the invention will'be hereinafter noticed in connection with the more detailed description, and the construction and combination of parts by which the several objects are attained and which consti-.

tutes my invention is as hereinafter claimed.

In the accompanying two sheets of drawings, which form a part of this specification, Figure 1 is perspective view inwhich the reflector is partly broken away, showing one"- form of heater arranged for attachment to a gas-burner. Fig. 2 is a top view of the wire helices and supporting-bar, which constitute the chief radiating parts of the heater. Fig. I

3 is a front view, partly broken away, of a heating -.stove containing the burner and heat-radiating device illustrated. in'the preceding figures. Fig. 4 is a side view, partly broken away, of the stove.

Two horizontally-disposed wire helices 1 1 are the parts which are mainly concerned in the extraction, conversion, and radiation of the heat from the products of combustion 'upper edge ofthe burner-flame.

arising from the flame of a burner 2. The 'coils of these helices are intermeshed, and in order that they may more readily intermesh one is a right-hand coil and the other is a lefthand coil. The helices are curved or arched, so that the lower sides of both coils may lie close to without touchingthe upper edge of the flame, and the helices conform to this edge of the flame. A transverse supporting-bar 3 is threaded through the helices between the lines of intersection of the coils. This bar is of 'archedfor'm to give the desired shape to the helices and is of sufficient body and strength to keep its shape and preserve the shape of the helices when the helices and bar are softened by the heat from the flame. The bar is of a form which can be readily made by punching from sheet metal. There are two short parallel horizontal slits in the bar near each end forming upper and lower sections 4 4 and a middle section 5. The upper and lower sections are bent rearwardly from the plane of the .bar and the middle section is bent forwardly from the plane of the bar, thereby forming an eye ateach end. It will be seen that the cutting "of the slitsand forming of the eyes can take place at'the same time as the punching of the bars. The ends of the bar are supported by vertical wire standards 6 6, threaded through the eyes .with downwardly-turned ends 7 7, which also pass through the eyes. The downwardly-turned ends have a springaction away from the standards,which causes them to bind inthe eyes and support the ends of the bar by friction and permit of the bar being readily adjusted up and down on the standards to bring the helices in proper relation to the p The standards are at the ends of asingle piece of wire Whichis bent double at its middle point and coiled to form a socket 8, which engages the burner and supports the standards. Near the points where the ends are bent downwardly from'the standards, thereby forming loops 9 9, the wire is bent to form shoulders 10 10, which in the form shown in Figs. 1 and 2 support aconical reflector 11. This reflector also becomes heated and acts as a radiator. The reflector is slitted at 12 12 to receive the loops.

In Figs. 3 and 4 the foregoing structure is combined in a heating-stove, except that the conical reflector above the helices and burner is omitted. The helices and burner are supported within a casing 13, which is open at one side, as shown. The casing has a separate top 14, which is hinged at 15 and may be readily lifted by the handle 16 to give access to the interior for lighting the burner. This top serves as a reflector'and heat-radiator in the same manner as the conical reflector of the form first described. The casing is provided with a flue 17, through which the products of combustion can be drawn 01f by connection with a, chimney. Within the casing and below the burner is an inclined reflector 18, with downwardly-diverging corrugations. The reflector is bent or curved and forms approximately part of the frustum of a cone. The upper edge is bent to a smaller curve than the lower edge. The inclination of the reflector is such with reference to the location of the radiating-helices and the side opening in the casing that the heat will be reflected through the opening mainly in horizontal and downward directions. Such heat as may be reflected at too low an angle to pass out of the casing is reflected back into the casing by the rearwardly-inclined floor 19 to increase the heat in the casing instead of reflecting it upwardly outside of the casing, as would be the case'if the floor were horizontal or forwardly inclined.

I do not confine myself in my invention to all of the details herein described, as many of them may be varied or omitted without departing from the spirit of the invention, and I do not limit myself in its application to any particular form of burner or combustible material, although the constructions illustrated are intended for gas and the burner shown is suitable for a illuminating-flame. I prefer, however, a burner for an illuminating-flame, since there is the added advantage of light as well as heat, and the combustion in an illuminating-flame is particularly complete and the products of combustion are free from poisonous and ill-smelling gases.

What I claim as new, and desire to secure by Letters Patent of the United States, is- I a burner,a transverse supporting-bar thro ugh the helix for supporting the coils and means for supporting the ends of the bar from the burner with the helix above the burner-flame.

2. A heat-radiating device consisting of a wire helix adapted to be heated by the flame from a burner, a transverse supporting-bar for the helix, vertical wire standards with downwardly-turned ends for adj ustably supporting the ends of the bar, and a standardsupporting socket for engaging the burner.

3. A heat-radiating device consisting of a wire helix adapted to be heated by the flame from a burner, a transverse supporting-bar for the helix, a horizontally-disposed conical reflector, vertical wire standards with downwardly-turned ends for supporting the reflector and for adjustably supporting the ends of the bar, and a standard-supporting socket for engaging the burner.

4. A heat-radiating device consisting of two intermeshed wire helices adapted to be heated by the flame from a burner, a transverse supporting-bar for both helices, and means for supporting the ends of the bar from the burner with the helices above the burner-flame.

5. A heating-stove consisting of a casing open at one side, a burner within the casing, a heat-radiating device consisting of a wire helix adapted to be heated from the burner, a transverse supporting-bar for the helix, means for supporting the ends of the bar with the helix above the burner-flame and within the casing, and an inclined reflector within the casing and below the burner, the reflector having downwardly-diverging corrugations.
